The observational campaign carried out on May 15-24, 2002, as part of the FluTuA Program, is described here. During 10 days, 5 minute averaged measurements of (a) solar radiation fluxes (incoming and outcoming) and long wave radiation fluxes (atmospheric and surface emission), at 6 m above the sea level; (b) air temperature, relative humidity and horizontal wind components, at 11 m and (c) sea surface temperature were gathered continuously. These observations were carried out on board of the Brazilian Navy Ship (Comte. Manhães), between Natal (60°S, 35.20°W) and Arquipelago de São Pedro e São Paulo (10°N, 29.30°W). The data was used to validate empirical expressions currently used to estimate turbulent energy components at the surface of the ocean. A preliminary characterization of the air-sea interaction in the Tropical Atlantic is also discussed.
